ASTM E – 14 – Standard Practice for Contact Ultrasonic Testing of Welds Using Phased Arrays

The values given in parentheses are for information only. Scanning speed speed at which the probe is manually moved forward axtm backward will be limited by the system update capabilities.

In some cases a phased array probe may be used without a refracting wedge or delay-line that is, just a hard wear-face surface. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Greater and lesser thicknesses may be tested using this standard practice if the technique can be demonstrated to provide adequate detection on mockups of the same wall thickness and geometry. Summary of Practice 4.

Practice E recommends methods of assessing performance characteristics of phased array probes and systems. The e27000 is intended to be used on thicknesses of 9 to mm 0.

Welds shall be inspected from both sides, where possible. Sensitivity amplitude reference standards that accomplish this are sidedrilled holes parallel to the major surfaces of the plate and perpendicular to the sound path,?

This technique is not generally considered to be as effective as the technique described in Fig. The practice is intended to be used on thicknesses of 9 to mm 0.

S-scans have the advantage over E-scans that all the speci? If the equipment has changed by more than the agreed upon tolerances, it shall be re-standardized. Set the signal from the reference re? Practice E covers setting up of phased arrays for weld inspections.

The modeled coverage in the upper portion of Fig. Note the f2700 responses from the side drilled holes is the same for each hole asstm though the angle used to detect the hole and the sound path to the hole is different in each instance. E — 09 7. The technique used will depend on whether or not the weld reinforcement has been ground? Other metallic materials can be examined using this practice provided reference standards can be developed that demonstrate that the particular material and weld can be successfully penetrated by an ultrasonic beam.

Therefore, it is necessary that the display used provide a uniform color code related to amplitude asstm all sound path distances.

While some scan patterns emulate manual technology, e270 scans for example, S-scans are unique to phased arrays. This practice provides procedural guidance for both manual and mechanized scanning of welds using phased array systems. Other metallic materials can be examined using this practice provided reference standards can be developed that demonstrate that the particular material and weld can be successfully penetrated by an ultrasonic beam.

More than one stand-off position may ast required for thicker sections. Apply the correction to all focal laws used for the examination.

Codes and code cases have been e27700, or are being developed, to cover phased array weld inspection requirements by organizations such as ASME. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
